Applicationxanuary 21, 1935, serial No. 2,684 l 1o claims. 11.12-7-33)The present invention relates in general to improvements in the art ofmanufacturing or repairing footwear, and relates more specifically toprovided with adjustable means for forcing the Y shoe proper intointimate contact with the upa.

per portion of the outsole at the'cement-coated surfaces. Whiletheseprior presses produce a relatively satisfactory union at the majorportions of the soles and shoes, they do not, in most cases, insureproper cementing of thesoles to the welts. This defect is due to thefact that the present presses ,do not provide for the exertion of properdownward pressure at the welts, in opposition to the elastic reactionpad, and it is impossible, with the prior practice, to produce perfectadhesion along the edge portions of the soles and welts, especially incases where the welts have been distorted due to prolonged use of theshoes. Although it has previously been attempted to provide appliancesfor securing such localized pressure at the welts, these prior deviceshave proven unsatisfactory and uncommercial mainly because they were toocomplicated and difficult to manipulate, and theywere not adapted toproperly cooperate with shoes of Various sizes and shapes.

It is therefore a more speciiic object of the present invention toprovide an improved appliance cooperable with shoe-soling presses of theabove-described general type, which will enhance the effectiveness ofsuch presses in securing perfect unions between the shoes and solesthroughout the entire contact areas. Another specific object of theinvention is to,-

provide a welt-engaging attachment for shoesoling 4presses, which isadapted to effectively comay be readily manipulated to effectivelycement a sole to the welt of arshoe.

A further specific object of the present invention is to provide, animproved accessory which is cooperable with any standard shoe-solingpress 5 so as to more effectively cement the soles to the shoes, andwhich may be manufactured and sold at moderate cost.-

These and other objects and advantages will be apparent from thefollowing detailed descrip- 10' tion. l

A clear conception of an embodiment of the invention and ofV the mode ofconstructing and of utilizing welt-engaging attachments built in ac- Ycordance with the improvement may be had by referring tov the drawing,accompanying and forming a, part of this specification, in which likereference characters designate the same or similar parts in thevariousviews.

Fig. 2 is a side elevation of the improved appliance, showing thev samecooperating with a shoe which is in engagement with an elastic pad, 25the latter being shown in section;

Fig. 3 is a transverse, vertical section through the assemblage of Fig.2, taken along the line V3---3 of Fig. 2,; and

Fig. 4 is an enlarged, transverse, vertical sec- 30 tion through oneside of the improved appliance.

While the invention Yhas been illustrated and described herein as beingprimarily adapted for embodiment in an appliance for shoe-repairingpresses, it is not intended to unnecessarily restrict the scope by suchspecic embodiment since some'of the novel features may obviously beapplicable to other types of shoe-manufacturing or repairing machinery.Y y

Referring to the drawing, the ordinary shoe- 40 repair press forattaching soles to the shoes by adhesion comprises in general an elasticreaction pad 6 upon which the sole 1 of a shoe 8 may be positionedduring cementing of the sole to the shoe, and a vertically adjustablespindle 9 45 cooperable with a pressure block l0, which is, in turn,cooperable with a last H to urge the shoe 8 and sole 1-toward theelastic padY 6. These, various elements of the shoe-repair press arerelatively old and well known and are shown in 50 greater detail inYunker Patent No.r 1,943,356,u granted January 16, 1934,A and in Yunkerapplication Serial No. 680,580, filed July 15, 1933.
